2 | twitterbot | |
3 | ||
4 | A twitter IRC bot. Twitterbot connected to an IRC server and idles in | |
5 | a channel, polling a twitter account and broadcasting all updates to | |
6 | friends. | |
7 | ||
8 | USAGE | |
9 | ||
10 | twitterbot [config_file] | |
11 | ||
12 | CONFIG_FILE | |
13 | ||
14 | The config file is an ini-style file that must contain the following: | |
15 | ||
16 | [irc] | |
17 | server: <irc_server> | |
18 | port: <irc_port> | |
19 | nick: <irc_nickname> | |
20 | channel: <irc_channels_to_join> | |
21 | prefixes: <prefix_type> | |
22 | ||
23 | [twitter] | |
24 | oauth_token_file: <oauth_token_filename> | |
25 | ||
26 | ||
27 | If no config file is given "twitterbot.ini" will be used by default. | |
28 | ||
29 | The channel argument can accept multiple channels separated by commas. | |
30 | ||
31 | The default token file is ~/.twitterbot_oauth. | |
32 | ||
33 | The default prefix type is 'cats'. You can also use 'none'. | |
